Overview
The DS3992Z-18N+ is a cold cathode fluorescent lamp (CCFL) controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a fixed frequency range of 40kHz to 80kHz and supports frequencies from 180Hz to 440Hz for specific control functions. The device features negative polarity output and is housed in a 16-pin SOIC package with dimensions of 150 mils. It is designed for use in lighting and ballast applications, providing reliable control for high-voltage inverter stages required in CCFL backlight systems.
Feature Summary
- Integrated CCFL controller for backlight systems
- Fixed operating frequency range of 40kHz to 80kHz
- Negative polarity output configuration
- Compatible with standard 16-SOIC surface-mount packaging
Applications
- CCFL backlight inverters
- Lighting ballast controllers
- High-voltage inverter stage control
Procurement Notes
Verify the exact suffix N+ against official datasheets to confirm pinout and electrical characteristics. Confirm availability status as supply may be restricted or limited depending on region. Ensure compatibility with existing PCB footprint for 16-SOIC packages before integration into new designs.
Selection Notes
Select this component when a dedicated CCFL controller with a fixed 40kHz-80kHz frequency range is required. It is suitable for applications needing negative polarity drive signals. Consider the 16-SOIC package size for space-constrained board layouts. Verify thermal performance requirements against the specified operating temperature range of -40°C to +85°C.
Part Context
This part belongs to the Maxim Integrated line of lighting and ballast controllers. It is specifically engineered for driving cold cathode fluorescent lamps in display and lighting applications. The device integrates necessary control logic for stable inverter operation.
Replacement Considerations
Check for direct pin-to-pin replacements within the same family. Verify if updated versions with extended temperature ranges or different package options are available from the manufacturer.
